Workloads and standard time norms in garment engineering
Zvonko Dragičević, Daniela Zavec Pavlinič, Jelka Geršak, 2002, original scientific article

Abstract: Posibilities of new methods for measuring loading and standard time norms are presented, as applied in the field of garment engineering. Measurements deescribed are performed on modern measuring equipment designed to measure and perform computer analysis of temporal values of processing parameters in sewing operation and simultaneously record in two planes using a video system. The measuring system described was used to investigate sewing operation for the seam on a ladies' fashion suit, 52 cm long. For the operation investigated, method of work employing the MTM (Methods Time Measurements) system with analysis of basic movements was selected. The MTM system used shows that normal time for the operation in question is around 429.3 TMU (15.5 s). Investigations of workload imposed on the worker according to the OADM method were done simultaneously, and total ergonomic loading coefficients of Ker=0.082 was established, thus determining the time necessary to organise the process of work as 464.5 TMU (16.7 s). Simultaneous measurements of time and dynamic changes of processing parameters, as well as logical sets of movements, are important for defining favourable operation structures, time norms ergonomically designed systems of work and workplaces in garment engineering, as early as in the phase of designing operation. The investigations described make possible to find optimal distribution of working elements and zones of reach important for ergonomic designing and/or re-designing of workplaces, which results in considerably reduced level of fatigue in work optimal quality level, higher degree of utilisation of equipment installed and lower manufacturing costs.
